REFLECTOR: Aileron balance

[Pat Shea]

Al,

I think the simple answer in in-trail. You could
always compare the difference between the wing aligned
with the incidence gauge versus leveled using the
wing's leading and trailing edges (chord line level).
I suspect it would be negligible for balancing
purposes. One trick for checking the aileron balance
with the ailerons installed is to temporarily replace
the hinge pins with wire of slightly smaller diameter.
I think I used the wire from some clothing hangars.
The ailerons hung freely and always came back to the
same position after being moved.
